PlCKER-OPERATING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters IPatent No. 464,908, datedDecember 8, 1891.

Application filed December 26, 1890. Serial No. 375,797. (No model.)

To all whom it may concern.-

Be it known that I, LEONARD L. ALLEN, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Picker- Operating Mechanism for Looms; and I do herebydeclare the following to be a full, clear, and exhad to the accompanyingdrawings, forming a part of this specification, and to the figures ofreference marked thereon.

My present invention has for its objects to provide an improved devicefor operating loom-pickers, whereby not only will the parts ers operatedwith less noise than heretofore, but the movement of the pickers can beregulated to a nicety and started and stopped gradually or abruptly, asmay be desired.

The invention has further for its objects to provide a cheap serviceabledevice that shall be simple in construction and easily applied to loomsnow in use, if desired, without material alteration; and to these endsit consists in certain novelties of construction and combinations ofparts, all as will be hereinafter fully described, and the novelfeatures pointed out particularly in the claims at the end of thisspecification.

In the drawings, Figure 1 is a vertical section of a loom, taken nearone end and showin g the application of my invention, thepicker-actuating frame being shown in section. Fig. 2 is a plan view ofthe picker-actuating frame; Fig. 3, a sectional view showing the laymoved back; Fig. 4, a perspective view of the actuating-frame, and Fig.5 a section of a detail.

Similar figures of referenceindicate similar parts.

I have not deemed it necessary to show all the operative parts of a loomin the accompanying drawings, but only so'much thereof as will exhibitclearly one means of carrying out my invention, nor to show but onepickcr-actuating mechanism, the one on the other end of the lay being inall respects the same.

Referring to the drawings, the figure 1 innary or any preferredconstruction; 2, a crossbeam; 3, a cross-shaft or tie-rod, and a thelay, pivoted at 5 and oscillated, as usual, by a pitman 6 from a shaftbearing a crank 7, and to which is connected a gear 8, meshing with gear9 on a shaft 10, which latter may be the driving-shaft or a drivenshaft, if de-.

rocated back and forth by a pitman 14, connected to one arm of abell-crank lever 15, pivoted on a bracket on cross beam 2, the other armof said lever being provided with a friction-roller 16, arranged in agroove in the face of cam 17, secured to the shaft 1O,

the parts and cam being so arranged that at each revolution of the shaft10 the lay will be moved forward to beat up the weft and the frame 13moved forward and back. The extreme outer sides of the frame 13 areformed by bars shaped, preferably, to correspond with the ways inwhichthe frame reciprocates, and just inside these side pieces are arrangedplates 18, each provided with a series of perforations 19 near one end,through which project the ends of a rod 20, provided, preferably, withthreaded ends and extending diagonally across the frame; but said rod,instead of being straight, I prefer to curve slightly in theconstructionshown; but this curve and the angleand shape of the rod canbe changed, as desired, by bending it and adjusting the ends in theapertures in plates 18, where they may be secured by suitabledevicessuch as nuts 21arranged on opposite sides of the plates, asshown.

Secured to the ways for the frame are suit able transversely-extendingguide-rods 22, forming ways for a sliding cross-head 23, connected by alink 24 to the picker-stick 25, sup ported on a suitable universalconnection 26, said picker-stick being connected by a rod 27 with thepicker 28, operating in the slotted end of the lay, as usual. The rod 27is arranged to slide in eyes or staples 29 on the back of the lay, andthe connection between it and the picker-stick is formed by passing itthrough an aperture enlarged on the outer side, as shown in dottedlines, Fig.

The cross-head 23, which embraces the guides 22 and the rod 20, ispreferably formed, as in Fig. 1, of a staple-shaped lower portion havingthe friction-roller 30 on its lower trans verse bar and the verticalrollers 31 on the legs, said lower roller operating against the lowerguide-rod and the rollers 31 against the sides of all three rods. Theupper portion of the cross-head consists of a plate 32, having afriction-roller 33 arranged in bearings on its lower side, whichoperates on the upper guiderod, said plate being secured to the ends ofthe staple-legs by nuts and being further provided on its upper sidewith a loop or eye 34, to which the link 24 is connected, as shown.

While in the present embodiment I have shown and described a specificconstruction of the cross-head, I do not desire to be confined to thisform, as others could as well be devised which would answer the purposeequally well; but the present construction of parts I have found. to beadmirably adapted for the purpose.

The cam operating the picker-actuating mechanism on the other side ofthe loom from that herein shown is arranged in the same positionrelative to the lay-oscillating devicesthat is to say, while the lay ismoved forward to beat up the weft the rollers on the ends of thebell-crank lever are in those portions of the cam-tracks concentric withthe shaft and with the pickers at the outward portion of the shuttle-boxat rest, as shown in Fig. 1; but as the cams revolve the eccentric partsof the cams, which occupy but a small part of the circle, move thebell-crank levers and reciprocate the frame 13 forward, as in dottedlines, and back quickly, the rod 20 causing the cross-heads andconsequently the pickers to move in and out rapidly, driving the shuttlefrom its contained box across the lay, as will be understood, thisoperation being repeated as rapidly as desired. Of course the cams 17,operating the picker-actuating frame, may have as many eccentricportions as desired, so as to cause two or more movements of the pickerat each oscillation of the more rapid, as will be understood.

It will be noted, also, that while in my present construction I haveshown the actuatingrod 20 and its frame inside the lower frame, which Ido in order to economize room,necessitating the employment of themechanism shown or its equivalent for transmitting the motion to thepicker at the lay ends, it is obvious that it could be placed in anyother position desired and other means employed for transmitting themotion of the cross-head actuated by it to the picker; also, thatinstead of actuating the frame 13 directly from the cam the parts couldreadily be turned at right angles to the position shown and thecrosshead actuated by the cam, while the frame carrying the rod could beconnected directly to the picker-stick, such modification being a mererearrangement of the parts and so obvious that its illustration hereinis deemed unnecessary.

One of the most desirable features of the invention being a rod or staffactuating piece arranged and preferably adjustable in a movablecarrying-frame, it is immaterial whether this adjustment is accomplishedby adjusting one or both ends or by changing the shape of theactuating-piece, which latter in the present construction is a rodcapable of being bent. Instead of making the actuating-piece in ameasure flexible, or even adjustable, it could be made rigid and newones of different shape inserted, when desirable or necessary, to causea different motion for the picker.
